In my (admittedly limited) experience with these films the colour disappears in strong alkaline solytion. So using "modern" low-alkali developers, acid stop and acid fix preserves the maximum colour. Try an "old-style" carbonate or hydroxide developer, and the film is colourless!
You could even try washing it in a nice strong alkali, and see if it helps...
